This PR contains a replacement driver for Intel iWarp hardware. This new
driver supports the old ethernet hardware and also newer chips that can do
ROCE. Otherwise this contains the typical mix of patches:
- Driver updates and cleanups for bnxt_re, cxgb4, mlx4, and mlx5
- Many static checker driven code clean ups, including a wide refcount_t
conversion
- Several series for the hns driver, more HIP09 HW capabilities, migration
to new HW register manipulators, and code cleanups
- Minor fixes and improvements in srp, rts, and cm
- Improvements throughout for sysfs related code to use DEVICE_ATTR_*,
make the ib_port sysfs first-class, and overall use sysfs APIs properly
- Intel's new irdma driver replacing i40iw
- rxe general clean ups and Memory Window support

group in error cases. Otherwise, there is a possibility of a sleep while
atomic. However, since 43c73221b3 ("ext4: replace BUG_ON with WARN_ON

ext4_grp_locked_error.

The MPTCP receive path is hooked only into the TCP slow-path.
The DSS presence allows plain MPTCP traffic to hit that
consistently.
Since commit e1ff9e82e2 ("net: mptcp: improve fallback to TCP"),
when an MPTCP socket falls back to TCP, it can hit the TCP receive
fast-path, and delay or stop triggering the event notification.
Address the issue explicitly disabling the header prediction
for MPTCP sockets.

Normally, if a reset fails due to failover or other communication error
there is another reset (eg: FAILOVER) in the queue and we would process
that reset. But if we are unable to communicate with PHYP or VIOS after
H_FREE_CRQ, there would be no other resets in the queue and the adapter
would be in an undefined state even though it was in the OPEN state
earlier. While starting the reset we set the carrier to off state so
we won't even get the timeout resets.
If the last queued reset fails, retry it as a hard reset (after the
usual 60 second settling time).

ptp: support virtual clocks and timestamping
Current PTP driver exposes one PTP device to user which binds network
interface/interfaces to provide timestamping. Actually we have a way
utilizing timecounter/cyclecounter to virtualize any number of PTP
clocks based on a same free running physical clock for using.
The purpose of having multiple PTP virtual clocks is for user space
to directly/easily use them for multiple domains synchronization.

| SO_TIMESTAMPING new flag: | Packets with
| SOF_TIMESTAMPING_BIND_PHC | TX/RX HW timestamps

+--------------------------------------------+
The block diagram may explain how it works. Besides the PTP virtual
clocks, the packet HW timestamp converting to the bound PHC is also
done in sock driver. For user space, PTP virtual clocks can be
created via sysfs, and extended SO_TIMESTAMPING API (new flag
SOF_TIMESTAMPING_BIND_PHC) can be used to bind one PTP virtual clock
for timestamping.
The test tool timestamping.c (together with linuxptp phc_ctl tool) can
be used to verify:

Since PTP virtual clock support is added, there can be
several PTP virtual clocks based on one PTP physical
clock for timestamping.
This patch is to extend SO_TIMESTAMPING API to support
PHC (PTP Hardware Clock) binding by adding a new flag
SOF_TIMESTAMPING_BIND_PHC. When PTP virtual clocks are
in use, user space can configure to bind one for
timestamping, but PTP physical clock is not supported
and not needed to bind.
This patch is preparation for timestamp conversion from

Support ptp physical/virtual clocks conversion via sysfs.
There will be a new attribute n_vclocks under ptp physical
clock sysfs.
- In default, the value is 0 meaning only ptp physical clock
is in use.
- Setting the value can create corresponding number of ptp
virtual clocks to use. But current physical clock is guaranteed
to stay free running.
- Setting the value back to 0 can delete virtual clocks and back
use physical clock again.
Another new attribute max_vclocks control the maximum number of
ptp vclocks.

This patch is to add ptp virtual clock driver framework
utilizing timecounter/cyclecounter.
The patch just exports two essential APIs for PTP driver.
- ptp_vclock_register()
- ptp_vclock_unregister()

DMAC based packet filtering
Each MAC block supports 32 DMAC filters which can be configured to accept
or drop packets based on address match This patch series adds mbox
handlers and extends ntuple filter callbacks to accomdate DMAC filters
such that user can install DMAC based filters on interface from ethtool.
Patch1 adds necessary mbox handlers such that mbox consumers like PF netdev
can add/delete/update DMAC filters and Patch2 adds debugfs support to dump
current list of installed filters. Patch3 adds support to call mbox
handlers upon receiving DMAC filters from ethtool ntuple commands.
Change-log:
v2 -
- fixed indentation issues.
v3 -
- fixed kdoc warnings

DMAC filtering can be achieved by either NPC MCAM rules or
CGX/RPM MAC filters. Currently we are achieving this by NPC
MCAM rules. This patch offloads DMAC filters to CGX/RPM MAC
filters instead of NPC MCAM rules. Offloading DMAC filter to
CGX/RPM block helps in reducing traffic to NPC block and
save MCAM rules

MAC block supports 32 dmac filters which are logically
divided among all attached LMACS.
For example MAC block0 having one LMAC then maximum supported
filters are 32 where as MAC block1 having 4 enabled LMACS
them maximum supported filteres are 8 for each LMAC.
This patch adds mbox handlers to add/delete/update mac entry
in DMAC filter table.

If one entered io_req_task_work_add() not seeing PF_EXITING, it will set
a ->task_state bit and try task_work_add(), which may fail by that
moment. If that happens the function would try to cancel the request.
However, in a meanwhile there might come other io_req_task_work_add()
callers, which will see the bit set and leave their requests in the
list, which will never be executed.
Don't propagate an error, but clear the bit first and then fallback
all requests that we can splice from the list. The callback functions
have to be able to deal with PF_EXITING, so poll and apoll was modified
via changing io_poll_rewait().

Since we don't really use req->task_work anymore, get rid of it together
with the nasty ->func aliasing between ->io_task_work and ->task_work,
and hide ->fallback_node inside of io_task_work.
Also, as task_work is gone now, replace the callback type from
task_work_func_t to a function taking io_kiocb to avoid casting and
simplify code.

When task_work_add() fails, we use ->exit_task_work to queue the work.
That will be run only in the cancellation path, which happens either
when the ctx is dying or one of tasks with inflight requests is exiting
or executing. There is a good chance that such a request would just get
stuck in the list potentially hodling a file, all io_uring rsrc
recycling or some other resources. Nothing terrible, it'll go away at
some point, but we don't want to lock them up for longer than needed.
Replace that hand made ->exit_task_work with delayed_work + llist
inspired by fput_many().

ASan reports a memory leak caused by evlist not being deleted on exit in
perf-report, perf-script and perf-data.
The problem is caused by evlist->session not being deleted, which is
allocated in perf_session__read_header, called in perf_session__new if
perf_data is in read mode.
In case of write mode, the session->evlist is filled by the caller.
This patch solves the problem by calling evlist__delete in
perf_session__delete if perf_data is in read mode.
Changes in v2:
- call evlist__delete from within perf_session__delete
v1: https://lore.kernel.org/lkml/20210621234317.235545-1-rickyman7@gmail.com/

In perf annotate, when 's' is pressed on a line containing source code,
it shows the message "Only available for assembly lines".
This patch gets rid of the error, moving the cursr to the next available
asm line (or the closest previous one if no asm line is found moving
forwards), before hiding source code lines.
Changes in v2:
- handle case of no asm line found in
annotate_browser__find_next_asm_line by returning NULL and
handling error in caller.
